'They (Wieden + Kennedy) have managed to revive a tired old brand from the 1970s that even my dad would be ashamed to use and created a genuinely hilarious piece of 30 second joy,' says the piece of the ad 'that hasn't aired in Britain but has become a global internet hit'.

For many years it was thought
the Davidson clan would die out but thanks to the herculean efforts of
one Ran Sax Holst, a baby son and heir to W+K's own Creative Director Tony was born at 0.43am on 24th March
2010.  Spike Mikael Sax Davidson weighed in at a healthy 8lbs 7oz with
huge feet. 

Possibly there is some yeti in the Davidson DNA.

Mother and baby are doing fine and returned home from
hospital on 25th March.  Father is still in a state of shock and in need
of several baby head wetting sessions.
